I doubt that very many of the people in question deserve much of an entry or mention and those that do are generally known by their common names, although, for example, Elizabeth Windsor, is almost unrecognizable by her common name.
I believe that there is a technical sense in which Elizabeth has no surname. That is, while the royal family, as an abstract entity unto itself, has the name "Windsor", its individual members do not.
I think that the most important thing is to establish a list of all the reasonably likely forms that naive links will take and a policy that they should all be created, as redirects or disambiguation pages (depending). Which of these forms is chosen as the naming convention is less important (as long as its an unambiguous one).
